To relieve the stress on channel estimation and decoding complexity in cell-free massive
multiple-input multiple-output (MIMO) systems, user grouping problem is investigated in this …

In this paper, we study the performance of reconfigurable intelligent surfaces (RISs) in a
multicell broadcast channel (BC) that employs improper Gaussian signaling (IGS) jointly with …

Internet of Video Things (IoVT) brings much higher requirements on the transmission and
computing capabilities of wireless networks than the traditional Internet of Things (IoT). Non …

This letter studies the performance of power beacon (PB) assisted downlink cooperative non-
orthogonal multiple access (NOMA) in a wireless powered communication network (WPCN) …

Non-orthogonal multiple access (NOMA) is a highly promising multiple access strategy for
wideband communication systems due to its high spectral efficiency. However, in multi-cell …

This article studies data aggregation in large-scale regularly deployed Internet of Things
(IoT) networks. The data granularity, in terms of information content and temporal resolution …

Limited backhaul bandwidth and blockage effects are two main factors limiting the practical
deployment of millimeter wave (mmWave) networks. To tackle these issues, we study the …

Driven by massive connections and exponential growth of data in mobile devices, Non-
orthogonal multiple access (NOMA) has become a candidate access technology to meet the …

The user grouping has a significant impact on the performance of non-orthogonal multiple
access (NOMA) systems. The present work is focused on downlink NOMA user grouping …

Integrated terrestrial-satellite networks (ITSNs) are the promising trends of future networks.
However, there exist great challenges when performing video multicast in ITSNs due to the …
